Just for a moment there I had a vision of you on your bike towing a MGBGT sports car (soft top in British Racing Green of course),with a lengthy set of jumper cables going from your hub to under the bonnet.Dunno why. Good fun indeed Tim.Glad I shook the mothballs out of my wallet and made the queen blink having not seen daylight for so long.....I think its going to turn out to be a great investment.

I've already had my money's worth just from the kick of mucking around hooking up batteries and gadgets and learning about it all. I have actually learnt a bit about simple electronics. Wish I had enough muscle to power an MGB, not to mention the house. Power bills, blooooody hell.Lucky there's not much traffic around here. I spend half my time on the road making sure those little LED's are flashing, ended up in the gravel a couple of times.You never know, all this junk might come in handy on a real tour some day. I'm hoping to do a long one some time but for one reason or another I'm restricted to short overnighters for the present. I really envy and admire all you guys doing the big tours.The journals and reports make for great reading. Oh well, one day.

I'm starting to lose track of who's used what combination, so if you see a combination you have used and know definitely works, please let me know the row number and I'll put a great big "Y" in that column

Seems to take slightly longer to charge the attached devices with the lights turned on, but still doable. Ride for a few solid hours at a reasonable speed and you're laughing.

I really have to find some time to update my blog. I'm currently settling back into work and house-hunting. So things have been hectic over the past few days to say the least considering I only got back to Oz a couple of days ago..

And this charges on-the-go (without an intermediary battery like the minigorilla or the e-werk cache). Please confirm and I'll update the spreadsheet

Also, have we confirmed that this combination works for on-the-go charging?

Hub dynamo + E-Werk + No cache + Garmin 800

Sorry if this has been answered before. I hope that the spreadsheet will represent a nice summary for future reference

Dynamo + eWerk + eWerk cache battery = charged GPS/iPad/iPhone/netbook (with the caveat that one must remember to charge the voltage and current output before plugging the device in).

Max

Hi Max,my "take" on the instructions is a little different.Far as I can make out, no changing of the voltage and current output when using the cache battery. (page 13 bottom of blue box)The manual says "Settings for cache battery 461A: 5.6 volts / 1.5 Amps"

Thanks for that, rifraf So (and I'm sorry to get into the minutiae), if your Garmin is dead, and you want to charge it whilst using it, is the formula

SonDelux + E-Werk + Cache Battery (set to 5.6v/1.5a) + Garmin

Or can we get away with

SonDelux + E-Werk + Garmin (plugged straight into the E-Werk)

Or will either way work? My question is around whether the cache battery is an absolute requirement to charge the Garmin whilst it is in use.

Ewerk will charge Garmin without cache battery. But when you stop it tells you it's lost charge and then start it beeps again. On Audax rides 300km or more needs a charge most times so Ewerk fine for that, unless it's raining. Then I'd be charging up the Ewerk battery and have the caps on it so it waterproof. When stop for lunch etc I would be charging it up with the battery. Or riding and charging when it's not raining.

btw someone over on bentrideronline forums has converted a 70mm sturmey archer drum brake single sided to containing a dynamo and may be going commercial with the kit. So I could end up with an alternative for my trike

After a large download of a compatibility pack for my now ancient 2003 Office Pro ,I can now see your Excel sheet.Thank you for your huge effort Max A great idea on your part and a fantastic resource for those who follow in our tyre prints (footsteps etc).CheersAidan

So I've dropped some cash on an E-werk, an E-werk cache, and a minigorilla. I know I can probably do what I need without the E-werk cache, but I'm keen to try a number of combinations and document the results. I've ordered it from Bike24, and expect based on rifraf's experience that it will take a couple weeks to get here.

My mum told me she wanted a solar charger for her phone and GPS. Thanks to you guys and my spreadsheet, I was able to tell her not to worry with that since she has a dyno, and there's an e-werk on the way

This only outputs 5V via USB (so it won't charge everything on the planet), but could be "one size fits most" solution. Quite cheap too, at around $68USD.

Interesting product. For me, I am thinking this might be a good option for the likes of Audax rides and at a reasonable price. The lack of battery kills it as a touring option in my context.

My concerns relate to the wiring. Number one being the lack of connectors which can be a pain in terms of SON dynamos given the size of their connectors. The other relates to the light connection. Maybe I am missing something there, but as I read the review there is only one wire to the light. Lights such as my Busch & Muller Lumotec IQ Cyo Senso Plus use two wires. This seems to raise an issue with this device or I am missing something.

The second wire gets twisted to one of the other two coming out of the unit - effectively that's the earth wire.I got connectors from Jaycar but haven't yet found a type that I'm fully happy with

I am sorry but I am not following you. Currently I have two connection points on the SON 28 and I have a wire with two strands that run directly from the light to the dynamo. There is nothing going to the bike as an earth for example. So if this only has one wire going to the light I am wondering how this work if the light requires to wires connected to the dynamo.

Oh well figure not for me. Earth wire not in use for the Son28 + supernova gear.

My Mini Gorilla has arrived It came fully charged and is busy topping up my workmate's phone. It was dead an hour ago and is now at 70% charged. The Mini Gorilla's battery is still full.

Now if only the e-Werk would arrive, I'd be a happy girl.
